Description

Technical Field

[0001] The utility model relates to the technical field of paper production, in particular to a device for extruding, shaping and drying paper molds. Background Art

[0002] Cardboard, also known as paperboard, is a thick paper sheet made from various pulps and composed of interwoven fibers. With the rapid development of the papermaking industry, the market demand for paper continues to increase, requiring the production process to be more efficient and faster. Extrusion, shaping, and drying are key links in paper production, and their efficiency directly affects the production capacity of the entire production line.

[0003] For example, the patent with publication number CN213514901U discloses a cardboard drying and heat-setting device. In the cardboard drying and heat-setting device, the heating element heats the air blown in by the blower and discharges it into the interior of the processing box to bake the cardboard. After the cardboard is dehydrated, the conveyor belt pushes the cardboard out through the cardboard on the right side. The structure is simple, easy to operate, reduces losses during production, and saves costs.

[0004] The above patent can only perform hot air drying on the bottom of the cardboard, but the top surface of the cardboard cannot be dried by hot air, and the drying requirement of the top surface of the cardboard is ignored, resulting in a significant temperature difference and humidity difference between the top and bottom of the cardboard during the drying process. This uneven drying method not only affects the overall quality of the cardboard, but also causes paper deformation and curling problems. Since the top surface of the cardboard cannot be directly affected by hot air, its drying speed is inevitably slower than the bottom, resulting in a longer time for the entire drying process, which not only reduces the overall efficiency of the production line, but also increases energy consumption and production costs.

A connecting plate 82 is arranged on one side of the fixing plate 81, and the connecting plate 82 is connected to the shell 83, so as to expand the blowing range and improve the drying efficiency.

[0030] Specifically, first, the staff starts the driving motor to drive the feed roller 2 at the output end to drive the cardboard to move toward the middle of the frame plate 1. The two groups of feed rollers 2 are driven by the gear set, so that the two groups of feed rollers 2 squeeze the cardboard to prevent wrinkles, so that the transmitted cardboard falls into the upper surface of the conveyor belt 3 and is transmitted to the middle.

[0032] See also Figure 5-Figure 6 The water absorbing structure 9 includes a long plate 91 arranged at the top of the frame plate 1, an electric push rod 92 is arranged on one side of the long plate 91, and a collecting box 93 is arranged at the output end of the electric push rod 92. The length of the collecting box 93 is greater than the width of the extrusion plate 5, and a scraper 94 is arranged on the top of the collecting box 93. The scraper 94 is used to scrape off the condensed beads evaporated by the hot air on the bottom surface of the extrusion plate 5, and a vertical plate 95 is arranged on the top of the collecting box 93. The vertical plates 95 are symmetrically arranged in two groups. The two groups of vertical plates 95 are rotatably connected to the opposite sides of each other with a rotating rod 96, and one end of the two groups of rotating rods 96 is provided with a cotton block 97, which is in contact with the side surface of the extrusion plate 5.

By driving the electric push rod 92 on one side of the long plate 91, the long plate 91 is connected to the frame plate 1, and the electric push rod 92 drives the collecting box 93 at the output end to move toward the extrusion plate 5. The scraper 94 at the top of the collecting box 93 contacts the bottom surface of the extrusion plate 5, so that the scraper 94 scrapes the water droplets on the bottom surface of the extrusion plate 5 into the inside of the collecting box 93, and the cotton column 98 absorbs the water droplets on the bottom surface of the extrusion plate 5, and the cotton blocks 97 at both ends of the cotton column 98 absorb the water droplets on the side surface of the extrusion plate 5. The cotton blocks 97 and the cotton column 98 are rotated by the rotating rod 96, and the rotating rod 96 is rotatably connected to the vertical plate 95, and the vertical plate 95 is connected to the collecting box 93, which is convenient for absorbing the water droplets on the bottom and sides of the extrusion plate 5, avoiding the extrusion plate 5 with water droplets squeezing the cardboard, and increasing the drying time.
